In order to minimize the dependencies depending on your needs, we provide these features under different packages.
servant, which contains everything you need to declare a webservice API.servant-server, which lets you implement an HTTP server with handlers for each endpoint of an API.servant-client, which lets you derive automatically Haskell functions that let you query each endpoint of aservantwebservice.servant-docs, which lets you generate API docs for your webservice.servant-js, which lets you derive Javascript functions (using vanilla JS ajax requests, angular or jquery) to query your API's endpoints, in the same spirit asservant-client.servant-blazeandservant-lucidprovide easy HTML rendering of your data as anHTMLcontent-type "combinator".
